Distances to objects in space are very, very large. The nearest star (excluding the Sun), Alpha Centauri, is 41.23 trillion km, or 41,320,000,000,000 km!!

You may know that Jupiter is the largest planet in the Solar System, but do you know how much larger than the Earth it is?

Find out by creating a scale model of each planet in our Solar System!

Impact craters are made when a space rock (called a meteorite or asteroid) hits a rocky planet or moon. The impact makes a round hole in the surface, called a crater.

The Sun is a constant presence in our life on Earth. It gives us the heat and light we need to survive. But it is not a stable place. The Sun is a ball of hot plasma which is constantly changing.

You have probably seen the Moon in the sky, but have you ever studied it in detail?
